This invention relates to packing rings for use in engines and in all devices in which rings are necessary and has for its principal object to rovide a device of this nature 8 which wil take up the wear'in the piston ring grooves 7 -,Another important object of the invention is to providea device of this nature 4 having a comparatively'simple and eflicient loconstruction, one which is reliable in use,'] nexpensive to..manufature, durable, and

well adapted designed. g V

With the above and numerous other objects in view as will appearas the description progresses the invention resides in certain novel features of construction, and in the combination and arrangement of parts as willbe hereinafter more fully-described Q and claimed. r

Inthe drawingf: V Figure 1 is an edge elevation of the de-' vice embodying my invention, 1

Figure 2 is a section therethrough taken substantially-on the line 2.2 of Figure 5,

-Figure 3 is a section taken-substantially on the line 3+3 of Figure 1, f

Figure 4 is a section taken substantially on the line 44 of Figure 1, and t Figure 5 is an edge elevation ofthe ring taken at right angles to the view. shown in Figure 1.

Referring to the drawing iii-detail it Will to the purpose for which itis be seen that the ring is spht longitudinally u and transversely so as to form a pair of diminating' at a point ofiset from the point of termination of the lower fingers.

verging fingers 1 anda second pair 2.

"These fingers 1 and 2 extend from the body 3. The upper fingers of each pair terminate adjacent each other as-do thelower fingers of each pair. .The upper ifingers of each 40 pair arecurved away from the lower fingers. 'Theterminals of theu'pper fingers are offset from the terminals of the lower fingers as is clearly shown in Figure 5. g

Having thus described my invention what 46 I- claim as new is' 1.: A piston ring of the class described be ing'split longitudinally and transversely to form two pair of fingers, the fingers in each a pair diverging from each other. 50

'2. A piston ring of the class described including abody of curved structure, a pair of diverging fingers extending from one side of the body and curved throughout their length, and a similar pair of fingers extending from the other side a of the body, the upper fingers of the two pairs of fingers ter- 3. A. piston ring of the class described ineluding a body. of'curved structure, a pair of diverging-fingers extending from one side of Y the body and curved throughout their length and a similar pair of fingers extending from the other side of the body,'the upper fingers of the two pairs of fingers terminating adacent each other offset, from the terminations of the lower fingers.

In testimony whereof I affix my signature.
